IMPROVEMENT IN AXLES FOR VEHICLES.

Specicatipn formir g part of Letters Patent No. 154,676, dated September 1, 1374 application filed April 3o, 1874.

To all whom it may concern:

Be it known that I, GEORGE HUNT, of Prattsville, in the county of Greene and State of New York, have invented certain new and useful Improvements in Hubs, Boxes, and Axle-Trees Combined, for wagons and earriages and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

The nature of my invention consists in the construction and arrangement of an axle and hub for vehicles, as will be hereinafter more fully set forth.

ln the accompanying drawing, Figure 1 is a longitudinal section of my invention through the linear w of Fig. 2. Fig. 2 is a transverse section of Fig. 1 through the line y y. Fig. 3 is a side view of a part of the axle, and Fig. 4 is a transverse section of Fig. l through the line z z.

Arepresents the metal spindle, provided with circumferential bearings a a, the space inside of the axle-box, may be filled with any suitable lubricator. The spindle is formed with an extended arm, B, which is to be screwed into a wood axletree, C. Around the inner end of the spin.- dle A, anda short distance from the end of the axle-tree C, is formed a circumferential collar, b. The spindle A is made hollow from the outer end inward for a suitable distance, and the outer end of the spindle is stopped by a plug, d. The cavity in the spindle is to. be lled with oil, which will .pass out through passages e e on each side of the collar b. Suitable packing-rings, f f, are placed one on each side of this collar, to prevent the too rapid escape of the oil. D represents the axle-box, provided near its inner end with a collar, E', and around the inner end 0f axlebox is a groove, so as to form atrthe end a circumferential iiange 0r collar, b'. The axlebox is attached to the spindle by means of a bisected collar, E, hinged together, and provided with interior circumferential flanges,l

which fit over the collars b and b'. On the hinged collar E are lugs i i, which fit in notches made on the inner end of the axlebox. When the collar E is closed around the collars b b', the free ends are fastened by a latch-pin, h, and this secured by a springcatch, k, as shown in Fig. 3. The hub is formed of a center disk or ring, G, having upon both sides alternate spoke-inortises, formed by means of partitions or lianges m m cast thereon, said flanges forming V-shaped spaces between the spoke-mortises, which spaces are closed by means of slides n n. This construction renders the hub very light, and yet sufficiently strong for all purposes. ()n

the outer side of each dange'm is formed a rib, Y

o, which is to enter a corresponding groove in the spoke-tenon, and thus hold the spoke rmly in place. In the ends of the iianges m are made notches a2, into which fits a circular bead, p, on the inner side .of the collar El at one end of the hub, and a similar rib on the collar E2 at the other end of the hub. The hub is held on the box by aprojection or lug, r, entering a notch in the ring G. The collar E2 is held and tightened byga nut,'I1`l, screwed on the end of the axle-box D.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The hollow spindle A, provided with bearings a a, collar b, oil-passages c e, and plug d, all combined substantially as and for the purposes set forth.

2. The hinged flanged collar E, provided with latch-pin h and spring-catch la, in coinbination with the spindle A, havingcollar b, and the axle-box D, having collar b', all substantially as and for the purposes set forth.

3. The annular disk G, provided with the lianges m m, having ribs 0 ^o and the slides a n, combined substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own, I hereby atx my signature in presence of two witnesses.

GEORGE HUNT.
